To think that we are the only living beings in the universe is quite absurd. The Universe is made up of ninety-one billion light years and we have only discovered 4% of it and the rest is just dark matter. The idea is that of the ninety-six percent that has yet to be discovered, some theories claim to believe that there can be no such thing as life in the other ninety-six. There may be other galaxies, planets, black holes and perhaps even other dimensions unknown to man. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an original essay If we broadened our spectrum of what life is and what it contains beyond carbon- and water-based life forms; there may simply be more than millions of other species that have evolved differently, even have different forms of technology and ways of living. If other forms of life existed, what would they be like? Would they have gray skin and big, soulless black eyes, as the media usually portrays them, or would they be exactly like us and function the same way? It's amazing that humans can earn less than 1% to even get noticed in this universe. That undiscovered ninety-six percent is considered dark matter, where millions of planets, galaxies and different species could exist. There are approximately ten sextillion stars in the universe, that is, approximately ten thousand stars for every grain of sand on the earth. If one in five stars is somehow connected to the sun in our solar system, there are five hundred billion billion suns out there. Scientists also estimate that every fifth sun may have Earth-like planets that harbor life, and diverse species and environments. Conflicting theories have claimed that there are no other life forms out there, implying that our technology is not advanced enough, or that our planet earth is the only planet sufficient for life or even it is simply impossible, the that is out of this world, especially if there are more stars in the universe than people on earth. Many may say that the universe is like a sandbox because it has the ability to create and manipulate galaxies and planets. There are also many different theories based on life forms outside of our world. Like Probability Theory which estimates that there are one hundred to four hundred billion stars in our Milky Way and that half of the stars have planets, averaging about eight planets per star, with many moons. The probability that Earth is the only planet with life, even intelligent life, is one in eight hundred billion for planets. While this doesn't narrow the field by much, the scientist would use the Drake equation created by Dr. Frank Drake, plugging in seasonal estimated values ​​to replace the variables. One suggests that there are ten thousand civilized worlds in the Milky Way. Another theory is the Goldilocks Theory which states that some planets may be too cold for life. Some planets may be too hot for life and others may be perfect. The perfect planet would contain liquid water and have a moderate temperature. It is estimated that there are eight trillion planets in the universe, and if every one in eight had a star to keep the water liquid; this theory reduces the probability of being alone from one in eight billion to one in ten billion. These theories cannot be trusted, but they may be absolutely true. Soon NASA will have technology that can take us traveling light years to find out if any of these theories are true.
